StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 19 April 2026; the live site may have changed since.

Dev Toolkit — Fast, Free & No Login is partway there, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 19, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. The crawl picked up 6 technologies on this site, covering analytics, developer tools, web fonts, and frameworks. The stack includes Vue.js, Google Analytics, and Google Fonts.

For context, it's one of 40 launches on this exact stack.
